Hi, I'm not sure why the computer is doing this, but whenever I plug in the computer, the power supply starts buzzing, and the LED light that shows if the computer is on automatically turns on once I plug in the power. And if I push the on/off button the computer doesn't respond to it at all. Not sure why this is happening, but please help.

Sounds as if the Power Supply has gone out, or the MotherBoard has shorted and is gone. The easiest way to check would be to find a replacement Power Supply and install it.

Has the computer been plugged during an electrical storm without being plugged into a surge protector?

Thanks for your help, I guess it really is power supply failure, I'll just have to figure it out on my own now. Thank you very much!

Changing the power supply is really pretty easy.
See if this will help.

And they are pretty cheap also.

If you have a used computer store near by, a used PS usually runs $5 to $10. If you have a name brand be sure and tell the people who you are buying it from. I have a bunch of Dells and I can't use a standard PS. I have to use one built for that machine. On the other hand if it's a standard PS they are plentiful used and new not that expensive $20 to $40.
Like River_Rat said, it could be the MB. Had a capacitor went bad it the CPU power regulator. When it heated up it would make a shril high pitch noise then the computer would shut down. It that case I scraped the MB.

I accumilated info on this subject from the internet a few months ago, and have been living by it, even though I cannot say just how accurate it is:

~~~~~~~~~~~~~~~~~~~~~~~~~
DELL COMPUTERS

If built after August 98, it probably needs a Dell PSU.

May be able to use an "ATX power supply to Dell" converter in order to be replaced with a standard ATX power supply.

endpcnoise.com - $14.00

Exceptions:
P4 Dell models Dimension 4300, 4400, 8200

NOT AT ALL COMPATABLE WITH ADAPTER: Dell Dimension 8100

PC Power and Cooling Inc. sells power supplies for Dells: pcpow.com
~~~~~~~~~~~~~~~~~~~~~~~~~~

Does this look accurate to you, acklan? Thanks.

Interesting. I have 14 Dell GX1. 11 are up and running. The other 3 are loaded with OS and software but I have them in reserve just in case on of the setups fail.
All of them were made in 1999.
Thank you for the information.
